RAIL-JOINT.

v To all whom it may concern:

' Be. it known that I,-JOHAN BoBiAN, a sub- .jectof the Emperor of Austria, residing at Southwest, in the county of Westmoreland and State of Pennsylvania, have invented "certain new and useful Improvements in Rail-Joints, of which the following is a specification.

among its principal. objects the provision of a This inventionrelates to certain new and useful improvements in rail oints and has this type of device which is capable of being comparatively easily and cheaply manufacjtured and which is durable in construction as wellas capable'of effectively connecting meetingends of rails.

A further obJect of the present invention is the provision of a railjoint including a pair of splice bars adapted to interlock with ;the meeting ends of rails and with each other, the splice bars being effectively mainjoint.

QW-ith the above general objects in view and others'that will become apparent as the nature'of the invention is better understood, the same consists in the novel form,

-i"combination and arrangement of parts here- 'inafter more fully described, shown in the accompanying drawings and claimed.

In'the accompanying drawings, in which like reference characters indicate corresponding parts throughout the several views,

Figure 1 1s a plan view of the present invention shown applied to the meeting ends of two rail sections.

7 Fig. 2 is a side elevational view of the device shown in Fig. 1.

-Fig. 3 is a transverse sectional view of the present invention taken substantially upon line III-III of Fig. 1, the tie being shown in elevation and one of the splice bar dowels being illustrated partially in section and partly broken away.

Fig. 4 is a longitudinal sectional View of the device taken substantially upon line IV-IV of Fig. 2 and Fig. 5 is a perspective view of one of the splice bars partially broken away.

the provision of means for effectively joining the ends 5 and 6 of meeting rails and includes a pair of splice bars 7 and 8 provided with a longitudinal groove in one side face of each of the same as at 9 adapted for snug reception of the base flanges of the rail ends 5 and 6 as clearly shown in Fig. 3, the splice bars 7 and 8 being arranged upon opposite sides of said rail ends. The inner v'erticalwalls' of the grooves 9 of the splice bars7 and 8 are provided with inwardly extending lugs 10 arranged to enter recesses 11 of similar form which are provided in the side' edges of the base flanges of the rail ends. This construction is designed to 'sointerlock the splice bars and rail ends as to prevent longitudinal movements of the same relative to each other and g the splice bar 7 is provided at points adjacent the center thereof with a pair of integral inwardly projecting dowel pins 12 which are adapted to extend through the apertures 13 and 1 1 provided in the webs of the rail ends 5 and 6 and to enter the sockets 15 and 16 provided in the splice bar 8 so as to cooperate with the interlocking connections 10 and 11 to preventrelative movement of the rail ends and splice bars.

Each of the splice bars 7 and 8 is pro videdwith longitudinal ribs 17 which are arranged to engage the under faces of the balls of the rail ends 5 and 6 so as to effectively prevent any depression of the rail ends at a point between the ties 18.

In Order to maintain the splice bars in theiroperative positions relative to the rail ends 5 and 6, said splice bars are tapered at their outer sides in both directions from the center of the length thereof so as to provide pairs of converging walls 19 and 20 respectively for the splice bars 7 and 8. Tie blocks 21 of similar construction are provided with grooves 22 in the upper faces thereof so that the same may be readily slid toward each other to Wedge the splice bars 7 and 8 together at which time the tie blocks 21 are seated upon the ties 18 and are there suitably secured as by means of spikes 23 which are driven through the perforations 24: of the bases of the blocks 21 and into the ties 18.

In order to insure sufficient strength, the tie blocks 21 are constructed with the upwardly extending lugs 25 thereof of a comparatively great width and the same are inlieved that the construction and operation clined outwardly and downwardly and provided with grooves 26 so as to insure the drainage of water away from the joint.

In Operation, the rail ends 5 and 6, which have been previously provided with the recesses 11, in the base flanges thereof, are placed in alinement as shown in Fig. 1 and thes'plice bars 7 and 8 are arranged upon opposite sides of the same as shown more clearly in Fig. 4 with the lugs 10 engaging the recesses 11 and with the dowels 12 arranged within the sockets15 and 16 and extending through .the apertures 13 and 14 of said rail ends. The tie blocks 21 are then slid toward each other so that they smaller ends of the splice bars? and S are received I within the grooves 22. Further movement of the tie blocks 21;toward each other causes engagement of the sidewalls of the grooves .22 with the tapered walls 19 and 20 of the splice bars 7 and 8, thus causing said splice bars to be firmly clamped and retained in their operative positions with theblock s 21 resting on the ties 18. The spikes 23' are then driven into the plates and ties and the rail ends 5 and 6 are effectively joined.

From the foregoing description, it is be as well as the advantages of the present invention will be readilyunderstood, by those skilled inthe art, and while the form of the the meeting ends of rails, of a pair of splice bars arranged at opposite sides thereof and having interlocking connection with the base flanges of said rail ends, said splice bars be ing provided with oppositely tapered outer Copies of this-patent may be obtained fer five cents each, by addressing the Washington, D. 0.

side walls, and tie blocks'having tapered grooves slidably receiving said splice bars to wedgingly clamp the same against the rail ends, substantially as described.

2. In a rail joint, the combination with the meeting ends of rails, of splice bars arranged at opposite sides thereof and provided with oppositely tapered. outer side walls, interlockingconnections between said rail ends and said splice bars, dowels carried by one of said splice bars and extending through said rail ends, the other splicebar being provided with sockets within which said dowels are seated, and means to clamp. said splice bars against said rail ends in}. cluding apair of tie blocks.

3. A rail joint comprisingthe combina-' tion with the meeting ends of rails provided with recessesv in the outer edges of the base flanges thereof, of a pair of splice bars provided with longitudinal grooves adapted for reception offsaid base flanges of the rails and provided with inwardly; directedlu'gs seated within said recesses, said splice bars being vprovided with oppositely tapered outer side walls, and apair of tie blocks pr vided with tapered grooves adapted for "the reception ofsaid splice bars to wedgethe lat-- ter toward each other and maintain the rails connected. v I

4. Ina boltless rail joint, apai'r ofsplice bars provided with longitudinal grooves adapted for the reception of the base flanges of meeting rail ends, and provided with oppositely tapered outer side walls, means carried by said splice bars adapted for interlocking engagement with said rail ends, and tie blocks provided with tapered grooves adapted for slidablereception of said splice bars to clamp the latter-against the opposite sides of said rail ends.
